material, at all times, and, as the material is discharged at the bottom of the chute, fresh material flows into the top of the chute, so thatthe material flowing through the chute wi'llbe carried to the discharge point with practically no breakage,

It will be understood that the reeving of the ropes may be modified without departing from the main feature of the invention, as, in some instances, a single reevingmay only be necessary, while in other cases ditional reeving may be required.

lVhile I have shown one means attached to the upper and lower ends of the telescopic chute for lengthening or shortening it, equivalent means may be used without departing from the spirit of the invention.

I claim:

1. The combination of a telescopic chute; a frame at the bottom of the chute; a frame from which the top of the chute is suspended; a second frame at the top of the chute; two ropes, one rope connecting the frame, which is attached to the upper end of the chute, to the supporting structure; means for operating the rope, the other rope frames; two ropes, one rope passing around,

the sheaves on the supporting structure and around the supporting frame at the upper end of the chute, the other rope passing around sheaves on the supporting structure and down to and around sheawes on the lower frame, then up and around the sheaves on the intermediate frame and down to the lower frame and up over a sheave on the supporting structure so that, when the last mentioned rope is manipulated, the chute can be increased or diminished in length and, when both ropes are manipulated, the

e chute can be raised bodily towards the sup port.
